COSH

Description: Returns the hyperbolic cosine of a number.

Syntax: COSH(Number)

• Number is any real number for which you want to find the hyperbolic cosine.

Remarks:

• The formula for the hyperbolic cosine is:

• When used in an event analysis flowchart, Number must evaluate to a numerical value. It can include:

• Numerical values

• Standard operands (+, -, *, /)

• Predefined mathematical functions (exp, log, sin, etc.)

• Event analysis internal functions

• Event analysis resources

• References to any ReliaSoft Workbooks

Example:

• COSH(4) = 27.30823 [the hyperbolic cosine of 4]
